Abstract

The utility model relates to a novel hot-water heat-supplying circulation device,which comprises a circulation loop including a boiler , a circulation pump and the heat consumers connected with each other through closed loop pipeline , the circulation loop is provided a water tank, make-up water pump and a check valve; The quantity of circulation pump is one; a by-pass pipe is arranged between the water main and backwater trunk, the by-pass valves are arranged in middle of by-pass pipe . Because only one circulation pump is arranged in heat-supply device instead of a plurality of pump parallel connected with each other, the conventional check valve is cancelled , furthermore, the by-pass pipe and by-pass valve are arranged between the water main and backwater trunk in parallel connection, as a result ,the equipment investment is reduced and the resistance in heat-supply device is lowered dramatically, the circulation pump is always ensured to operate in high-efficiency zone so that the operation cost is decreased and the energy is saved obviously.

Description

Novel hot water heat supply EGR
Technical field
The utility model relates to the heat supply process field, is specifically related to a kind of novel hot water heat supply EGR.
Background technology
Energy savings is a big problem that is related to national economy, is the heating enterprise of community service for direct consumes energy, and energy savings is even more important.Facts have proved that under the prerequisite that guarantees qualified heating quality, the energy consumption of unit area of heat-supply service depends primarily on the technical merit of heating enterprise.The present various heating plants that use ubiquity in design significantly technological deficiency, as: unreasonable, the multiple operating condition of water circulating pump type selecting is simple to adopt many parallels connection of pumps, water circulating pump outlet that check-valves etc. is installed unreasonably, therefore cause the construction investment height, the operating cost height, a series of problems that energy waste is serious.
The utility model content
The purpose of this utility model is to overcome existing heating plant deficiency technically, and a kind of novel hot water heat supply EGR simple in structure, reasonable in design, effectively energy savings is provided.
The purpose of this utility model is achieved through the following technical solutions: this novel hot water heat supply EGR comprise boiler, with boiler by the closed water circulating pump that is connected of pipeline with above-mentioned boiler and water circulating pump by the closed hot user who is connected of the pipeline heat supply closed circuit of composition jointly; In the described boiler of this closed circuit, water circulating pump and hot user's import and export pipeline, be respectively arranged with gate valve; Described water circulating pump is one; Between total water main of water circulating pump and boiler and total backwater main, be provided with bypass pipe, be connected to by-passing valve in the bypass pipe inter-burst.
The utility model also is provided with the dirt separator that is serially connected in the closed circuit in the water circulating pump inlet ductwork gate valve outside.Small pump check-valves, small pump and the water tank that is connected with this loop arranged in the closed circuit outer setting.
The beneficial effects of the utility model are: because a water circulating pump only is set in the heat supply EGR, substitute many parallels connection of pumps of the prior art, cancelled the check-valves of installing on the traditional handicraft, and in boiler pipe one side parallel connection bypass pipe and by-passing valve, not only reduced equipment investment, significantly reduced the heating plant internal resistance, guaranteed that simultaneously water circulating pump always works in efficient district, thereby reduced operating cost, effectively saved the energy.
Description of drawings
Below in conjunction with embodiment and accompanying drawing thereof, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model hot water heating EGR.
1. boilers, 2. water circulating pumps, 3. hot user's 4. gate valves 5. Pressure gauges 6. dirt separators 7. water tanks 8. small pumps 9. small pump check-valves 10. bypass pipes 11. by-passing valves among the figure.
The specific embodiment
As shown in Figure 1, form the heat supply closed circuit jointly by boiler 1, water circulating pump 2 and hot user 3, wherein water circulating pump 2 is by pipeline and 1 closed connection of boiler, and hot user 3 is connected by pipeline is closed with boiler 1 and water circulating pump 2; In boiler 1 described in this closed circuit, water circulating pump 2 and hot user 3 import and export pipelines, be respectively arranged with gate valve 4, be used to regulate discharge.The maximum characteristics of this heat supply EGR are to have cancelled the water circulating pump check-valves that generally is arranged in the prior art in water circulating pump 2 export pipelines, to reduce circulation resistance, in heating plant, only be provided with a water circulating pump 2 exactly in addition and work independently, substitute many parallels connection of pumps of generally using in the prior art; Reasonable selection for water circulating pump 2 is very important, during design, must carry out waterpower according to actual conditions and calculate definite pump head.Facts have proved, adopt technique scheme not only to reduce equipment investment, can also improve the service efficiency of water circulating pump 2, make it remain on the operation of efficient district, thereby in guaranteeing heating plant, under the prerequisite of the good circulation of water and normal heat supply, accomplish effective energy savings.
At boiler 1, water circulating pump 2 and the hot user 3 common heat supply closed circuit outer setting of forming water tank 7, small pump 8 and the small pump check-valves 9 that is connected with this loop arranged, being the closed circuit moisturizing as required; In the pipeline of above-mentioned small pump check-valves 9 exits and small pump porch, also be respectively arranged with the gate valve 4 that is used to regulate current.Between total water main of water circulating pump 2 and boiler 1 and total backwater main, be provided with bypass pipe 10, be connected to by-passing valve 11 in these bypass pipe 10 inter-burst; When the work of heat supply EGR moves, regulate the aperture of by-passing valve 11, boiler 1 is moved by the specified water yield, and the water greater than the boiler 1 specified water yield is flow through in the heat supply network by bypass pipe 10, can effectively reduce the body resistance of boiler 1 like this, reduce the power attenuation of water circulating pump 2.
In water circulating pump 2 inlet ductwork gate valves 4 arranged outside the dirt separator 6 that is serially connected in the closed circuit is arranged, the effect of described dirt separator 6 is to remove because of construction remains in foreign material in the pipe network, the suspension in the filtering recirculated water, and dirt separator 6 inlet sides also are serially connected with gate valve 4.In the described water circulating pump 2 outlet side pipelines and all be furnished with Pressure gauge 5 in hot user 3 export pipelines, in order to monitoring with understand the operation conditions of hot water heating EGR.
